It's not just “Single Sign-on” by Steve Knott (aurionPro SENA)

- by Greg Jensen

It is true that Oracle Enterprise Single Sign-on (Oracle ESSO) started out as purely an application single sign-on tool but as we have seen in the previous articles in this series the product has matured into a suite of tools that can do more than just automated single sign-on and can also provide rapidly deployed, cost effective solution to many demanding password management problems. In the last article of this series I would like to discuss three cases where customers faced password scenarios that required more than just single sign-on and how some of the less well known tools in the Oracle ESSO suite “kitbag” helped solve these challenges. Case #1 One of the issues often faced by our customers is how to keep their applications compliant. I had a client who liked the idea of automated single sign-on for most of his applications but had a key requirement to actually increase the security for one specific SOX application. For the SOX application he wanted to secure access by using two-factor authentication with a smartcard. The problem was that the application did not support two-factor authentication. The solution was to use a feature from the Oracle ESSO suite called authentication manager. This feature enables you to have multiple authentication methods for the same user which in this case was a smartcard and the Windows password. Within authentication manager each authenticator can be configured with a security grade so we gave the smartcard a high grade and the Windows password a normal grade. Security grading in Oracle ESSO can be configured on a per application basis so we set the SOX application to require the higher grade smartcard authenticator. The end result for the user was that they enjoyed automated single sign-on for most of the applications apart from the SOX application. When the SOX application was launched, the user was required by ESSO to present their smartcard before being given access to the application. Case #2 Another example solving compliance issues was in the case of a large energy company who had a number of core billing applications. New regulations required that users change their password regularly and use a complex password. The problem facing the customer was that the core billing applications did not have any native user password change functionality. The customer could not replace the core applications because of the cost and time required to re-develop them. With a reputation for innovation aurionPro SENA were approached to provide a solution to this problem using Oracle ESSO. Oracle ESSO has a password expiry feature that can be triggered periodically based on the timestamp of the users’ last password creation therefore our strategy here was to leverage this feature to provide the password change experience. The trigger can launch an application change password event however in this scenario there was no native change password feature that could be launched therefore a “dummy” change password screen was created that could imitate the missing change password function and connect to the application database on behalf of the user. Oracle ESSO was configured to trigger a change password event every 60 days. After this period if the user launched the application Oracle ESSO would detect the logon screen and invoke the password expiry feature. Oracle ESSO would trigger the “dummy screen,” detect it automatically as the application change password screen and insert a complex password on behalf of the user. After the password event had completed the user was logged on to the application with their new password. All this was provided at a fraction of the cost of re-developing the core applications. Case #3 Recent popular initiatives such as the BYOD and working from home schemes bring with them many challenges in administering “unmanaged machines” and sometimes “unmanageable users.” In a recent case, a client had a dispersed community of casual contractors who worked for the business using their own laptops to access applications. To improve security the around password management the security goal was to provision the passwords directly to these contractors. In a previous article we saw how Oracle ESSO has the capability to provision passwords through Provisioning Gateway but the challenge in this scenario was how to get the Oracle ESSO agent to the casual contractor on an unmanaged machine. The answer was to use another tool in the suite, Oracle ESSO Anywhere. This component can compile the normal Oracle ESSO functionality into a deployment package that can be made available from a website in a similar way to a streamed application. The ESSO Anywhere agent does not actually install into the registry or program files but runs in a folder within the user’s profile therefore no local administrator rights are required for installation. The ESSO Anywhere package can also be configured to stay persistent or disable itself at the end of the user’s session. In this case the user just needed to be told where the website package was located and download the package. Once the download was complete the agent started automatically and the user was provided with single sign-on to their applications without ever knowing the application passwords. Finally, as we have seen in these series Oracle ESSO not only has great utilities in its own tool box but also has direct integration with Oracle Privileged Account Manager, Oracle Identity Manager and Oracle Access Manager. Integrated together with these tools provides a complete and complementary platform to address even the most complex identity and access management requirements. So what next for Oracle ESSO? “Agentless ESSO available in the cloud” – but that will be a subject for a future Oracle ESSO series!

Reading All Users Session

- by imran_ku07

Introduction : InProc Session is the widely used state management. Storing the session state Inproc is also the fastest method and is well-suited to small amounts of volatile data. Reading and writing current user Session is very easy. But some times we need to read all users session before taking a decision or sometimes we may need to check which users are currently active with the help of Session. But unfortunately there is no class in .Net Framework (i don't found myself) to read all user InProc Session Data. In this article i will use reflection to read all user Inproc Session. Description : This code will work equally in both MVC and webform, but for demonstration i will use a simple webform example. So let's create a simple Website and Add two aspx pages, Default.aspx and Default2.aspx. In Default.aspx just add a link to navigate to Default2.aspx and in Default.aspx.cs just add a Session. Default.aspx: <%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default.aspx.cs" Inherits="Default" %><!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"><html ><head runat="server"> <title>Untitled Page</title></head><body> <form id="form1" runat="server"> <div> <a href="Default2.aspx">Click to navigate to next page</a> </div> </form></body></html> Default.aspx.cs: using System;using System.Data;using System.Configuration;using System.Collections;using System.Web;using System.Web.Security;using System.Web.UI;using System.Web.UI.WebControls;using System.Web.UI.WebControls.WebParts;using System.Web.UI.HtmlControls;public partial class Default : System.Web.UI.Page{ protected void Page_Load(object sender, EventArgs e) { Session["User"] = "User" + DateTime.Now; }} Now when every user click this link will navigate to Default2.aspx where all the magic appears.Default2.aspx.cs: using System;using System.Data;using System.Configuration;using System.Collections;using System.Web;using System.Web.Security;using System.Web.UI;using System.Web.UI.WebControls;using System.Web.UI.WebControls.WebParts;using System.Web.UI.HtmlControls;using System.Reflection;using System.Web.SessionState;public partial class Default2 : System.Web.UI.Page{ protected void Page_Load(object sender, EventArgs e) { object obj = typeof(HttpRuntime).GetProperty("CacheInternal", BindingFlags.NonPublic | BindingFlags.Static).GetValue(null, null); Hashtable c2 = (Hashtable)obj.GetType().GetField("_entries", BindingFlags.NonPublic | BindingFlags.Instance).GetValue(obj); foreach (DictionaryEntry entry in c2) { object o1 = entry.Value.GetType().GetProperty("Value", BindingFlags.NonPublic | BindingFlags.Instance).GetValue(entry.Value, null); if (o1.GetType().ToString() == "System.Web.SessionState.InProcSessionState") { SessionStateItemCollection sess = (SessionStateItemCollection)o1.GetType().GetField("_sessionItems", BindingFlags.NonPublic | BindingFlags.Instance).GetValue(o1); if (sess != null) { if (sess["User"] != null) { Label1.Text += sess["User"] + " is Active.<br>"; } } } } }} Now just open more than one browsers or more than one browser instance and then navigate to Default.aspx and click the link, you will see all the user's Session data. How this works : InProc session data is stored in the HttpRuntime’s internal cache in an implementation of ISessionStateItemCollection that implements ICollection. In this code, first of all i got CacheInternal Static Property of HttpRuntime class and then with the help of this object i got _entries private member which is of type ICollection. Then simply enumerate this dictionary and only take object of type System.Web.SessionState.InProcSessionState and finaly got SessionStateItemCollection for each user.Summary : In this article, I shows you how you can get all current user Sessions. However one thing you will find when executing this code is that it will not show the current user Session which is set in the current request context because Session will be saved after all the Page Events.

Adding AjaxOnly Filter in ASP.NET Web API

- by imran_ku07

Introduction: Currently, ASP.NET MVC 4, ASP.NET Web API and ASP.NET Single Page Application are the hottest topics in ASP.NET community. Specifically, lot of developers loving the inclusion of ASP.NET Web API in ASP.NET MVC. ASP.NET Web API makes it very simple to build HTTP RESTful services, which can be easily consumed from desktop/mobile browsers, silverlight/flash applications and many different types of clients. Client side Ajax may be a very important consumer for various service providers. Sometimes, some HTTP service providers may need some(or all) of thier services can only be accessed from Ajax. In this article, I will show you how to implement AjaxOnly filter in ASP.NET Web API application. Description: First of all you need to create a new ASP.NET MVC 4(Web API) application. Then, create a new AjaxOnly.cs file and add the following lines in this file, public class AjaxOnlyAttribute : System.Web.Http.Filters.ActionFilterAttribute { public override void OnActionExecuting(System.Web.Http.Controllers.HttpActionContext actionContext) { var request = actionContext.Request; var headers = request.Headers; if (!headers.Contains("X-Requested-With") || headers.GetValues("X-Requested-With").FirstOrDefault() != "XMLHttpRequest") actionContext.Response = request.CreateResponse(HttpStatusCode.NotFound); } } This is an action filter which simply checks X-Requested-With header in request with value XMLHttpRequest. If X-Requested-With header is not presant in request or this header value is not XMLHttpRequest then the filter will return 404(NotFound) response to the client. Now just register this filter, [AjaxOnly] public string GET(string input) You can also register this filter globally, if your Web API application is only targeted for Ajax consumer. Summary: ASP.NET WEB API provide a framework for building RESTful services. Sometimes, you may need your certain API services can only be accessed from Ajax. In this article, I showed you how to add AjaxOnly action filter in ASP.NET Web API. Hopefully you will enjoy this article too.

Configuring Oracle iPlanet WebServer / Oracle Traffic Director to use crypto accelerators on T4-1 servers

- by mv

Configuring Oracle iPlanet Web Server / Oracle Traffic Director to use crypto accelerators on T4-1 servers Jyri had written a technical article on Configuring Solaris Cryptographic Framework and Sun Java System Web Server 7 on Systems With UltraSPARC T1 Processors. I tried to find out what has changed since then in T4. I have used a T4-1 SPARC system with Solaris 10. Results slightly vary for Solaris 11. For Solaris 11, the T4 optimization was implemented in libsoftcrypto.so while it was in pkcs11_softtoken_extra.so for Solaris 10. Overview of T4 processors is here in this blog. Many thanx to Chi-Chang Lin and Julien for their help. 1. Install Oracle iPlanet Web Server / Oracle Traffic Director. Go to instance/config directory. # cd /opt/oracle/webserver7/https-hostname.fqdn/config 2. List default PKCS#11 Modules # ../../bin/modutil -dbdir . -listListing of PKCS #11 Modules-----------------------------------------------------------1. NSS Internal PKCS #11 Moduleslots: 2 slots attachedstatus: loadedslot: NSS Internal Cryptographic Servicestoken: NSS Generic Crypto Servicesslot: NSS User Private Key and Certificate Servicestoken: NSS Certificate DB2. Root Certslibrary name: libnssckbi.soslots: 1 slot attachedstatus: loadedslot: NSS Builtin Objectstoken: Builtin Object Token----------------------------------------------------------- 3. Initialize the soft token data store in the $HOME/.sunw/pkcs11_softtoken/ directory # pktool setpin keystore=pkcs11Enter token passphrase: olderpasswordCreate new passphrase: passwordRe-enter new passphrase: passwordPassphrase changed. 4. Offload crypto operations to Solaris Crypto Framework on T4 $ ../../bin/modutil -dbdir . -nocertdb -add SCF -libfile /usr/lib/libpkcs11.so -mechanisms RSA:AES:SHA1:MD5 Module "SCF" added to database. Note that -nocertdb means modutil won't try to open the NSS softoken key database. It doesn't even have to be present. PKCS#11 library used is /usr/lib/libpkcs11.so. If the server is running in 64 bit mode, we have to use /usr/lib/64/libpkcs11.so Unlike T1 and T2, in T4 we do not have to disable mechanisms in softtoken provider using cryptoadm. 5. List again to check that a new module SCF is added # ../../bin/modutil -dbdir . -list Listing of PKCS #11 Modules-----------------------------------------------------------1. NSS Internal PKCS #11 Moduleslots: 2 slots attachedstatus: loadedslot: NSS Internal Cryptographic Servicestoken: NSS Generic Crypto Servicesslot: NSS User Private Key and Certificate Servicestoken: NSS Certificate DB2.

Create certificate in “Sun Metaslot” : I have used certutil, but you must use Admin Server CLI / GUI # ../../bin/certutil -S -x -n "Server-Cert" -t "CT,CT,CT" -s "CN=*.fqdn" -d . -h "Sun Metaslot"Enter Password or Pin for "Sun Metaslot": password 7. Verify that the certificate is created properly in “Sun Metslaot” # ../../bin/certutil -L -d . -h "Sun Metaslot"Certificate Nickname Trust AttributesSSL,S/MIME,JAR/XPIEnter Password or Pin for "Sun Metaslot": passwordSun Metaslot:Server-Cert CTu,Cu,Cu# 8. Associate this newly created certificate to http listener using Admin CLI/GUI. After that server.xml should have <http-listener> ... <ssl> <server-cert-nickname>Sun Metaslot:Server-Cert</server-cert-nicknamer> </ssl> Note the prefix "Sun Metaslot" 9. Disable PKCS#11 bypass To use the accelerated AES algorithm, turn off PKCS#11 bypass, and configure modutil to have the AES mechanism go to the Metaslot. After you disable PKCS#11 bypasss using Admin GUI/CLI, check that server.xml should have <server> .... <pkcs11> <enabled>1</enabled> <allow-bypass>0</allow-bypass> </pkcs11> With PKCS#11 bypass enabled, Oracle iPlanet Web Server will only use the RSA capability of the T4, provided certificate and key are stored in the T4 slot (Metaslot). Actually, the RSA op is never bypassed in NSS, it's always done with PKCS#11 calls. So the bypass settings won't affect the behavior of the probes for RSA at all. The only thing that matters if where the RSA key and certificate live, ie. which PKCS#11 token, and thus which PKCS#11 module gets called to do the work. If your certificate/key are in the NSS certificate/key db, you will see libsoftokn3/libfreebl libraries doing the RSA work. If they are in the Sun Metaslot, it should be the Solaris code. 10. Start the server instance # ../bin/startserv Oracle iPlanet Web Server 7.0.16 B09/14/2012 03:33Please enter the PIN for the "Sun Metaslot" token: password...info: HTTP3072: http-listener-1: https://hostname.fqdn:80 ready to accept requestsinfo: CORE3274: successful server startup 11.

Clients for testing : You can use any browser. I used NSS tool tstclnt for testing $cat > req.txtGET /index.html HTTP/1.0 For checking both RSA and AES, I used cipher “:0035” which is TLS_RSA_WITH_AES_256_CBC_SHA $./tstclnt -h hostname -p 80 -d . -T -f -o -v -c “:0035” < req.txt 13.

B2B and B2C alike… but a little different – Oracle Commerce named Leader in Forrester B2B Commerce Wave

- by Katrina Gosek

We weren’t surprised to see Oracle Commerce positioned as a Leader in Forrester Research, Inc.’s first Commerce Wave focused on B2B, “The Forrester Wave™: B2B Commerce Suites, Q4 2013,” released earlier this month. We believe that the report validates much of what we’ve heard from our largest customers – the world’s largest distribution, manufacturing and high-tech customers who sell billions of dollars of goods and services to other businesses through their Web channels. More importantly, we feel that the report confirms something very important: B2B and B2C Commerce are alike… but a little different. B2B and B2C Commerce are alike… Clearly, B2C experiences have set expectations for B2B. Every B2B buyer is a consumer at home and brings the same expectations to a website selling electronic components, aftermarket parts, or MRO products. Forrester calls these rich consumer-based capabilities that help B2B customers do their jobs “table stakes”: front-office content, community, and commerce features that meet customer expectations for 24x7x365 ordering, real-time customer service, and expedited shipping — both online and on mobile devices: “Whether they are just beginning to sell online or are in the late stages of launching a next-generation site, B2B eCommerce operations today must: offer a customer experience standard comparable to what leading b2c sites now offer; address the growing influence that mobile devices are having in the workplace; make a qualitative and quantitative business case that drives sustained investment.” Just five years ago, many of our B2B customers’ online business comprised only 5-10% of their total revenue. Today, when we speak to those same brands, we hear about double and triple digit growth in their online channels. Many have seen the percentage of the business they perform in their web channels cross the 30-50% threshold. You can hear first-hand from several Oracle Commerce B2B customers about the success they are seeing, and what they’re trying to accomplish (Carolina Biological, Premier Farnell, DeliXL, Elsevier). It seems that this market momentum is likely the reason Forrester broke out the separate B2B Commerce Wave from the B2C Wave. In fact, B2B is becoming the larger force in commerce, expected to collect twice the online dollars of B2C this year ($559 billion). But a little different… Despite the similarities, there is a key and very important difference between B2C and B2B. Unlike a consumer shopping for shoes, a business shopper buying from a distributor or manufacturer is coming to the Web channel as a part of their job. So in addition to a rich, consumer-like experience this shopper expects, these B2B buyers need quoting tools and complex pricing capabilities, like eProcurement, bulk order entry, and other self-service tools such as account, contract and organization management. Forrester also is emphasizing three additional “back-end” tools and capabilities their clients say they need to drive growth in their B2B online channels: i) product information management (PIM), which provides a single system of record for large part lists and product catalogs; ii) web content management (WCM), needed to manage large volumes of unstructured marketing information, and iii) order management systems (OMS), which manage and orchestrate the complex B2B order life cycle from quote through approval, submission to manufacturing, distribution and delivery. We would like to expand on each of these 3 areas: As Forrester suggests, back-end PIM is definitely needed by B2B Commerce providers. Most B2B companies have made significant investments in enterprise-grade PIMs, given the importance of product data management for aggregation and syndication of content, product attribution, analytics, and handling of complex workflows. While in principle it may sound appealing to have a PIM as part of a commerce offering (especially for SMBs who have to do more with less), our customers have typically found that PIM in a commerce platform is largely redundant with what they already have in-place, and is not fully-featured or robust enough to handle the complexity of the product data sets that B2B distributors and manufacturers usually handle. To meet the PIM needs for commerce, Oracle offers enterprise PIM (Product Hub/Fusion PIM) and a robust enterprise data quality product (EDQP) integrated with the Oracle Commerce solution. These are key differentiators of our offering and these capabilities are becoming even more tightly integrated with Oracle Commerce over time. For Commerce, what customers really need is a robust product catalog and content management system for enabling business users to further enrich and ready catalog and content data to be presented and sold online. This has been a significant area of investment in the Oracle Commerce platform , which continue to get stronger. We see this combination of capabilities as best meeting the needs of our customers for a commerce platform without adding a largely redundant, less functional PIM in the commerce front-end. On the topic of web content management, we were pleased to see Forrester cite Oracle’s differentiated digital experience capability in this area and the “unique opportunity in the market to lead the convergence of commerce and content management with the amalgamation of Oracle Commerce with WebCenter Sites (formally FatWire).” Strong content management capabilities are critical for distributors and manufacturers who are frequently serving an engineering audience coming to their websites to conduct product research in search of technical data sheets, drawings, videos and more. The convergence of content, commerce, and experience is critical for B2B brands selling online. Regarding order management, Forrester notes that many businesses use their existing back-end enterprise resource planning (ERP) systems to manage order life cycles. We hear the same from most of our B2B customers, as they already have an ERP system—if not several of them—and are not interested in yet another one. So what do we take away from the Wave results? Forrester notes that the Oracle Commerce Platform “has always had strong B2B commerce capabilities and Oracle certainly has an exhaustive list of B2B customers using the solution.” What makes us excited about developing leading B2B solutions are the close relationships with our customers and the clear opportunity in the market – which we'll address in an exciting new release planned for the next 12 months. Oracle has one of the world’s largest B2B customer bases, providing leading solutions across key business-to-business functions – from marketing, sales automation, and service to master data management, and ERP.

Goodby jQuery Templates, Hello JsRender

- by SGWellens

A funny thing happened on my way to the jQuery website, I blinked and a feature was dropped: jQuery Templates have been discontinued. The new pretender to the throne is JsRender. jQuery Templates looked pretty useful when they first came out. Several articles were written about them but I stayed away because being on the bleeding edge of technology is not a productive place to be. I wanted to wait until it stabilized…in retrospect, it was a serendipitous decision. This time however, I threw all caution to the wind and took a close look at JSRender. Why? Maybe I'm having a midlife crisis; I'll go motorcycle shopping tomorrow. Caveat, here is a message from the site: Warning: JsRender is not yet Beta, and there may be frequent changes to APIs and features in the coming period. Fair enough, we've been warned. The first thing we need is some data to render. Below is some JSON formatted data. Typically this will come from an asynchronous call to a web service. For simplicity, I hard coded a variable: var Golfers = [ { ID: "1", "Name": "Bobby Jones", "Birthday": "1902-03-17" }, { ID: "2", "Name": "Sam Snead", "Birthday": "1912-05-27" }, { ID: "3", "Name": "Tiger Woods", "Birthday": "1975-12-30" } ]; We also need some templates, I created two. Note: The script blocks have the id property set. They are needed so JsRender can locate them. <script id="GolferTemplate1" type="text/html"> {{=ID}}: <b>{{=Name}}</b> <i>{{=Birthday}}</i> <br /> </script> <script id="GolferTemplate2" type="text/html"> <tr> <td>{{=ID}}</td> <td><b>{{=Name}}</b></td> <td><i>{{=Birthday}}</i> </td> </tr> </script> Including the correct JavaScript files is trivial: <script src="Scripts/jquery-1.7.js" type="text/javascript"></script> <script src="Scripts/jsrender.js" type="text/javascript"></script> Of course we need some place to render the output: <div id="GolferDiv"></div><br /> <table id="GolferTable"></table> The code is also trivial: function Test() { $("#GolferDiv").html($("#GolferTemplate1").render(Golfers)); $("#GolferTable").html($("#GolferTemplate2").render(Golfers)); // you can inspect the rendered html if there are poblems. // var html = $("#GolferTemplate2").render(Golfers); } And here's what it looks like with some random CSS formatting that I had laying around. Not bad, I hope JsRender lasts longer than jQuery Templates. One final warning, a lot of jQuery code is ugly, butt-ugly. If you do look inside the jQuery files, you may want to cover your keyboard with some plastic in case you get vertigo and blow chunks. I hope someone finds this useful. Steve Wellens CodeProject

How to propagate http response code from back-end to client

- by Manoj Neelapu

Oracle service bus can be used as for pass through casses. Some use cases require propagating the http-response code back to the caller. http://forums.oracle.com/forums/thread.jspa?messageID=4326052&#4326052 is one such example we will try to accomplish in this tutorial.We will try to demonstrate this feature using Oracle Service Bus (11.1.1.3.0. We will also use commons-logging-1.1.1, httpcomponents-client-4.0.1, httpcomponents-core-4.0.1 for writing the client to demonstrate.First we create a simple JSP which will always set response code to 304.The JSP snippet will look like <%@ page language="java" contentType="text/xml; charset=UTF-8" pageEncoding="UTF-8" %><% System.out.println("Servlet setting Responsecode=304"); response.setStatus(304); response.flushBuffer();%>We will now deploy this JSP on weblogic server with URI=http://localhost:7021/reponsecode/For this JSP we will create a simple Any XML BS We will also create proxy service as shown below Once the proxy is created we configure pipeline for the proxy to use route node, which invokes the BS(JSPCaller) created in the first place. So now we will create a error handler for route node and will add a stage. When a HTTP BS sends a request, the JSP sends the response back. If the response code is not 200, then the http BS will consider that as error and the above configured error handler is invoked. We will print $outbound to show the response code sent by the JSP. The next actions. To test this I had create a simple clientimport org.apache.http.Header;import org.apache.http.HttpEntity;import org.apache.http.HttpHost;import org.apache.http.HttpResponse;import org.apache.http.HttpVersion;import org.apache.http.client.methods.HttpGet;import org.apache.http.conn.ClientConnectionManager;import org.apache.http.conn.scheme.PlainSocketFactory;import org.apache.http.conn.scheme.Scheme;import org.apache.http.conn.scheme.SchemeRegistry;import org.apache.http.impl.client.DefaultHttpClient;import org.apache.http.impl.conn.tsccm.ThreadSafeClientConnManager;import org.apache.http.params.BasicHttpParams;import org.apache.http.params.HttpParams;import org.apache.http.params.HttpProtocolParams;import org.apache.http.util.EntityUtils;/** * @author MNEELAPU * */public class TestProxy304{ public static void main(String arg[]) throws Exception{ HttpHost target = new HttpHost("localhost", 7021, "http"); // general setup SchemeRegistry supportedSchemes = new SchemeRegistry(); // Register the "http" protocol scheme, it is required // by the default operator to look up socket factories. supportedSchemes.register(new Scheme("http", PlainSocketFactory.getSocketFactory(), 7021)); // prepare parameters HttpParams params = new BasicHttpParams(); HttpProtocolParams.setVersion(params, HttpVersion.HTTP_1_1); HttpProtocolParams.setContentCharset(params, "UTF-8"); HttpProtocolParams.setUseExpectContinue(params, true); ClientConnectionManager connMgr = new ThreadSafeClientConnManager(params, supportedSchemes); DefaultHttpClient httpclient = new DefaultHttpClient(connMgr, params); HttpGet req = new HttpGet("/HttpResponseCode/ProxyExposed"); System.out.println("executing request to " + target); HttpResponse rsp = httpclient.execute(target, req); HttpEntity entity = rsp.getEntity(); System.out.println("----------------------------------------"); System.out.println(rsp.getStatusLine()); Header[] headers = rsp.getAllHeaders(); for (int i = 0; i < headers.length; i++) { System.out.println(headers[i]); } System.out.println("----------------------------------------"); if (entity != null) { System.out.println(EntityUtils.toString(entity)); } // When HttpClient instance is no longer needed, // shut down the connection manager to ensure // immediate deallocation of all system resources httpclient.getConnectionManager().shutdown(); }}On compiling and executing this we see the below output in STDOUT which clearly indicates the response code was propagated from Business Service to Proxy serviceexecuting request to http://localhost:7021----------------------------------------HTTP/1.1 304 Not ModifiedDate: Tue, 08 Jun 2010 16:13:42 GMTContent-Type: text/xml; charset=UTF-8X-Powered-By: Servlet/2.5 JSP/2.1----------------------------------------

First toe in the water with Object Databases : DB4O

- by REA_ANDREW

I have been wanting to have a play with Object Databases for a while now, and today I have done just that. One of the obvious choices I had to make was which one to use. My criteria for choosing one today was simple, I wanted one which I could literally wack in and start using, which means I wanted one which either had a .NET API or was designed/ported to .NET. My decision was between two being: db4o MongoDb I went for db4o for the single reason that it looked like I could get it running and integrated the quickest. I am making a Blogging application and front end as a project with which I can test and learn with these object databases. Another requirement which I thought I would mention is that I also want to be able to use the said database in a shared hosting environment where I cannot install, run and maintain a server instance of said object database. I can do exactly this with db4o. I have not tried to do this with MongoDb at time of writing. There are quite a few in the industry now and you read an interesting post about different ones and how they are used with some of the heavy weights in the industry here : http://blog.marcua.net/post/442594842/notes-from-nosql-live-boston-2010 In the example which I am building I am using StructureMap as my IOC. To inject the object for db4o I went with a Singleton instance scope as I am using a single file and I need this to be available to any thread on in the process as opposed to using the server implementation where I could open and close client connections with the server handling each one respectively. Again I want to point out that I have chosen to stick with the non server implementation of db4o as I wanted to use this in a shared hosting environment where I cannot have such servers installed and run. public static class Bootstrapper { public static void ConfigureStructureMap() { ObjectFactory.Initialize(x => x.AddRegistry(new MyApplicationRegistry())); } } public class MyApplicationRegistry : Registry { public const string DB4O_FILENAME = "blog123"; public string DbPath { get { return Path.Combine(Path.GetDirectoryName(Assembly.GetAssembly(typeof(IBlogRepository)).Location), DB4O_FILENAME); } } public MyApplicationRegistry() { For<IObjectContainer>().Singleton().Use( () => Db4oEmbedded.OpenFile(Db4oEmbedded.NewConfiguration(), DbPath)); Scan(assemblyScanner => { assemblyScanner.TheCallingAssembly(); assemblyScanner.WithDefaultConventions(); }); } } So my code above is the structure map plumbing which I use for the application. I am doing this simply as a quick scratch pad to play around with different things so I am simply segregating logical layers with folder structure as opposed to different assemblies. It will be easy if I want to do this with any segment but for the purposes of example I have literally just wacked everything in the one assembly. You can see an example file structure I have on the right. I am planning on testing out a few implementations of the object databases out there so I can program to an interface of IBlogRepository One of the things which I was unsure about was how it performed under a multi threaded environment which it will undoubtedly be used 9 times out of 10, and for the reason that I am using the db context as a singleton, I assumed that the library was of course thread safe but I did not know as I have not read any where in the documentation, again this is probably me not reading things correctly. In short though I threw together a simple test where I simply iterate to a limit each time kicking a common task off with a thread from a thread pool. This task simply created and added an random Post and added it to the storage. The execution of the threads I put inside the Setup of the Test and then simply ensure the number of posts committed to the database is equal to the number of iterations I made; here is the code I used to do the multi thread jobs: [TestInitialize] public void Setup() { var sw = new System.Diagnostics.Stopwatch(); sw.Start(); var resetEvent = new ManualResetEvent(false); ThreadPool.SetMaxThreads(20, 20); for (var i = 0; i < MAX_ITERATIONS; i++) { ThreadPool.QueueUserWorkItem(delegate(object state) { var eventToReset = (ManualResetEvent)state; var post = new Post { Author = MockUser, Content = "Mock Content", Title = "Title" }; Repository.Put(post); var counter = Interlocked.Decrement(ref _threadCounter); if (counter == 0) eventToReset.Set(); }, resetEvent); } WaitHandle.WaitAll(new[] { resetEvent }); sw.Stop(); Console.WriteLine("{0:00}.{1:00} seconds", sw.Elapsed.Seconds, sw.Elapsed.Milliseconds); } I was not doing this to test out the speed performance of db4o but while I was doing this I could not help but put in a StopWatch and see out of sheer interest how fast it would take to insert a number of Posts. I tested it out in this case with 10000 inserts of a small, simple POCO and it resulted in an average of: 899.36 object inserts / second. Again this is just simple crude test which came out of my curiosity at how it performed under many threads when using the non server implementation of db4o. The spec summary of the computer I used is as follows: With regards to the actual Repository implementation itself, it really is quite straight forward and I have to say I am very surprised at how easy it was to integrate and get up and running. One thing I have noticed in the exposure I have had so far is that the Query returns IList<T> as opposed to IQueryable<T> but again I have not looked into this in depth and this could be there already and if not they have provided everything one needs to make there own repository. An example of a couple of methods from by db4o implementation of the BlogRepository is below: public class BlogRepository : IBlogRepository { private readonly IObjectContainer _db; public BlogRepository(IObjectContainer db) { _db = db; } public void Put(DomainObject obj) { _db.Store(obj); } public void Delete(DomainObject obj) { _db.Delete(obj); } public Post GetByKey(object key) { return _db.Query<Post>(post => post.Key == key).FirstOrDefault(); } … Anyways I hope to get a few more implementations going of the object databases and literally just get familiarized with them and the concept of no sql databases. Cheers for now, Andrew

OData to the rescue. Exposing the eventlog as a data feed

- by cibrax

In one of the project where I was working one, we used the Microsoft Enterprise Library Exception Application Block integration with WCF for logging all the technical issues on the services/backend in Windows Event Log. This application block worked like a charm, all the errors were correctly logged on the Event Log without even needing to modify the service code. However, we also needed to provide a quick way to expose all those events to the different system users so they could get access to all the them remotely. In just a couple of minutes I came up with a simple solution based on ADO.NET Data Services. ADO.NET data services is very powerful in this sense, you only need to provide a IQueryable implementation, and that’s all. You get a RESTful service with rich query support for free. In this sample, I used Linq to Objects to get the latest entries from the Event Log, and I also filter the entries by the category used by the Application Block to avoid loading unnecessary entries in memory. public class LogDataSource { string source; public LogDataSource(string source) { this.source = source; } public LogDataSource() { } public IQueryable<LogEntry> LogEntries { get { return GetEntries().AsQueryable().OrderBy(e => e.TimeGenerated); } } private IEnumerable<LogEntry> GetEntries() { var applicationLog = System.Diagnostics.EventLog.GetEventLogs().Where(e => e.Log == "Application") .FirstOrDefault(); var entries = new List<LogEntry>(); if (applicationLog != null) { foreach (EventLogEntry entry in applicationLog.Entries) { if (source == null || entry.Source.Equals(source, StringComparison.InvariantCultureIgnoreCase)) { entries.Add(new LogEntry { Category = entry.Category, EventID = entry.InstanceId, Message = entry.Message, TimeGenerated = entry.TimeGenerated, Source = entry.Source, }); } } } return entries.OrderByDescending(e => e.TimeGenerated) .Take(200); } } LogEntry is class I created for this service to expose an Event Log Entry. [EntityPropertyMappingAttribute("Source", SyndicationItemProperty.Title, SyndicationTextContentKind.Plaintext, true)] [EntityPropertyMapping("Message", SyndicationItemProperty.Summary, SyndicationTextContentKind.Plaintext, true)] [EntityPropertyMapping("TimeGenerated", SyndicationItemProperty.Updated, SyndicationTextContentKind.Plaintext, true)] [DataServiceKey("EventID")] public class LogEntry { public long EventID { get; set; } public string Category { get; set; } public string Message { get; set; } public DateTime TimeGenerated { get; set; } public string Source { get; set; } } As you can see, I used the new feature “Friendly feeds” to map several properties in the entries with standard ATOM elements. The “DataServiceKey” is only necessary because I am using the Reflection Provider (the exposed IQueryable implementation is just Linq to Objects) rather than the default Entity Framework Provider. The data service implementation is also quite simple, just a couple of lines were needed to expose the data source created previously. public class LogDataService : DataService<LogDataSource> { public static void InitializeService(IDataServiceConfiguration config) { config.SetEntitySetAccessRule("*", EntitySetRights.AllRead); } protected override LogDataSource CreateDataSource() { string source = ConfigurationManager.AppSettings["EventLogSource"]; if (source == null) { throw new ApplicationException("The EventLogSource appsetting is missing in the configuration file"); } return new LogDataSource(source); } } With this implementation in place, the final users not only get a feed with all the latest errors in the event log, but also support for performing queries against that data. This is one of the great things about ADO.NET Data services.

Skinny controller in ASP.NET MVC 4

- by thangchung

Rails community are always inspire a lot of best ideas. I really love this community by the time. One of these is "Fat models and skinny controllers". I have spent a lot of time on ASP.NET MVC, and really I did some miss-takes, because I made the controller so fat. That make controller is really dirty and very hard to maintain in the future. It is violate seriously SRP principle and KISS as well. But how can we achieve that in ASP.NET MVC? That question is really clear after I read "Manning ASP.NET MVC 4 in Action". It is simple that we can separate it into ActionResult, and try to implementing logic and persistence data inside this. In last 2 years, I have read this from Jimmy Bogard blog, but in that time I never had a consideration about it. That's enough for talking now. I just published a sample on ASP.NET MVC 4, implemented on Visual Studio 2012 RC at here. I used EF framework at here for implementing persistence layer, and also use 2 free templates from internet to make the UI for this sample. In this sample, I try to implementing the simple magazine website that managing all articles, categories and news. It is not finished at all in this time, but no problems, because I just show you about how can we make the controller skinny. And I wanna hear more about your ideas. The first thing, I am abstract the base ActionResult class like this: public abstract class MyActionResult : ActionResult, IEnsureNotNull { public abstract void EnsureAllInjectInstanceNotNull(); } public abstract class ActionResultBase<TController> : MyActionResult where TController : Controller { protected readonly Expression<Func<TController, ActionResult>> ViewNameExpression; protected readonly IExConfigurationManager ConfigurationManager; protected ActionResultBase (Expression<Func<TController, ActionResult>> expr) : this(DependencyResolver.Current.GetService<IExConfigurationManager>(), expr) { } protected ActionResultBase( IExConfigurationManager configurationManager, Expression<Func<TController, ActionResult>> expr) { Guard.ArgumentNotNull(expr, "ViewNameExpression"); Guard.ArgumentNotNull(configurationManager, "ConfigurationManager"); ViewNameExpression = expr; ConfigurationManager = configurationManager; } protected ViewResult GetViewResult<TViewModel>(TViewModel viewModel) { var m = (MethodCallExpression)ViewNameExpression.Body; if (m.Method.ReturnType != typeof(ActionResult)) { throw new ArgumentException("ControllerAction method '" + m.Method.Name + "' does not return type ActionResult"); } var result = new ViewResult { ViewName = m.Method.Name }; result.ViewData.Model = viewModel; return result; } public override void ExecuteResult(ControllerContext context) { EnsureAllInjectInstanceNotNull(); } } I also have an interface for validation all inject objects. This interface make sure all inject objects that I inject using Autofac container are not null. The implementation of this as below public interface IEnsureNotNull { void EnsureAllInjectInstanceNotNull(); } Afterwards, I am just simple implementing the HomePageViewModelActionResult class like this public class HomePageViewModelActionResult<TController> : ActionResultBase<TController> where TController : Controller { #region variables & ctors private readonly ICategoryRepository _categoryRepository; private readonly IItemRepository _itemRepository; private readonly int _numOfPage; public HomePageViewModelActionResult(Expression<Func<TController, ActionResult>> viewNameExpression) : this(viewNameExpression, DependencyResolver.Current.GetService<ICategoryRepository>(), DependencyResolver.Current.GetService<IItemRepository>()) { } public HomePageViewModelActionResult( Expression<Func<TController, ActionResult>> viewNameExpression, ICategoryRepository categoryRepository, IItemRepository itemRepository) : base(viewNameExpression) { _categoryRepository = categoryRepository; _itemRepository = itemRepository; _numOfPage = ConfigurationManager.GetAppConfigBy("NumOfPage").ToInteger(); } #endregion #region implementation public override void ExecuteResult(ControllerContext context) { base.ExecuteResult(context); var cats = _categoryRepository.GetCategories(); var mainViewModel = new HomePageViewModel(); var headerViewModel = new HeaderViewModel(); var footerViewModel = new FooterViewModel(); var mainPageViewModel = new MainPageViewModel(); headerViewModel.SiteTitle = "Magazine Website"; if (cats != null && cats.Any()) { headerViewModel.Categories = cats.ToList(); footerViewModel.Categories = cats.ToList(); } mainPageViewModel.LeftColumn = BindingDataForMainPageLeftColumnViewModel(); mainPageViewModel.RightColumn = BindingDataForMainPageRightColumnViewModel(); mainViewModel.Header = headerViewModel; mainViewModel.DashBoard = new DashboardViewModel(); mainViewModel.Footer = footerViewModel; mainViewModel.MainPage = mainPageViewModel; GetViewResult(mainViewModel).ExecuteResult(context); } public override void EnsureAllInjectInstanceNotNull() { Guard.ArgumentNotNull(_categoryRepository, "CategoryRepository"); Guard.ArgumentNotNull(_itemRepository, "ItemRepository"); Guard.ArgumentMustMoreThanZero(_numOfPage, "NumOfPage"); } #endregion #region private functions private MainPageRightColumnViewModel BindingDataForMainPageRightColumnViewModel() { var mainPageRightCol = new MainPageRightColumnViewModel(); mainPageRightCol.LatestNews = _itemRepository.GetNewestItem(_numOfPage).ToList(); mainPageRightCol.MostViews = _itemRepository.GetMostViews(_numOfPage).ToList(); return mainPageRightCol; } private MainPageLeftColumnViewModel BindingDataForMainPageLeftColumnViewModel() { var mainPageLeftCol = new MainPageLeftColumnViewModel(); var items = _itemRepository.GetNewestItem(_numOfPage); if (items != null && items.Any()) { var firstItem = items.First(); if (firstItem == null) throw new NoNullAllowedException("First Item".ToNotNullErrorMessage()); if (firstItem.ItemContent == null) throw new NoNullAllowedException("First ItemContent".ToNotNullErrorMessage()); mainPageLeftCol.FirstItem = firstItem; if (items.Count() > 1) { mainPageLeftCol.RemainItems = items.Where(x => x.ItemContent != null && x.Id != mainPageLeftCol.FirstItem.Id).ToList(); } } return mainPageLeftCol; } #endregion } Final step, I get into HomeController and add some line of codes like this [Authorize] public class HomeController : BaseController { [AllowAnonymous] public ActionResult Index() { return new HomePageViewModelActionResult<HomeController>(x=>x.Index()); } [AllowAnonymous] public ActionResult Details(int id) { return new DetailsViewModelActionResult<HomeController>(x => x.Details(id), id); } [AllowAnonymous] public ActionResult Category(int id) { return new CategoryViewModelActionResult<HomeController>(x => x.Category(id), id); } } As you see, the code in controller is really skinny, and all the logic I move to the custom ActionResult class. Some people said, it just move the code out of controller and put it to another class, so it is still hard to maintain. Look like it just move the complicate codes from one place to another place. But if you have a look and think it in details, you have to find out if you have code for processing all logic that related to HttpContext or something like this. You can do it on Controller, and try to delegating another logic (such as processing business requirement, persistence data,...) to custom ActionResult class. Tell me more your thinking, I am really willing to hear all of its from you guys. All source codes can be find out at here.

What do you think of this generator syntax?

- by ChaosPandion

I've been working on an ECMAScript dialect for quite some time now and have reached a point where I am comfortable adding new language features. I would love to hear some thoughts and suggestions on the syntax. Example generator { yield 1; yield 2; yield 3; if (true) { yield break; } yield continue generator { yield 4; yield 5; yield 6; }; } Syntax GeneratorExpression: generator { GeneratorBody } GeneratorBody: GeneratorStatementsopt GeneratorStatements: StatementListopt GeneratorStatement GeneratorStatementsopt GeneratorStatement: YieldStatement YieldBreakStatement YieldContinueStatement YieldStatement: yield Expression ; YieldBreakStatement: yield break ; YieldContinueStatement: yield continue Expression ; Semantics The YieldBreakStatement allows you to end iteration early. This helps avoid deeply indented code. You'll be able to write something like this: generator { yield something1(); if (condition1 && condition2) yield break; yield something2(); if (condition3 && condition4) yield break; yield something3(); } instead of: generator { yield something1(); if (!condition1 && !condition2) { yield something2(); if (!condition3 && !condition4) { yield something3(); } } } The YieldContinueStatement allows you to combine generators: function generateNumbers(start) { return generator { yield 1 + start; yield 2 + start; yield 3 + start; if (start < 100) { yield continue generateNumbers(start + 1); } }; }

Requesting Delegation (ActAs) Tokens using WSTrustChannel (as opposed to Configuration Madness)

- by Your DisplayName here!

Delegation using the ActAs approach has some interesting security features A security token service can make authorization and validation checks before issuing the ActAs token. Combined with proof keys you get non-repudiation features. The ultimate receiver sees the original caller as direct caller and can optionally traverse the delegation chain. Encryption and audience restriction can be tied down Most samples out there (including the SDK sample) use the CreateChannelActingAs extension method from WIF to request ActAs tokens. This method builds on top of the WCF binding configuration which may not always be suitable for your situation. You can also use the WSTrustChannel to request ActAs tokens. This allows direct and programmatic control over bindings and configuration and is my preferred approach. The below method requests an ActAs token based on a bootstrap token. The returned token can then directly be used with the CreateChannelWithIssued token extension method. private SecurityToken GetActAsToken(SecurityToken bootstrapToken) { var factory = new WSTrustChannelFactory( new UserNameWSTrustBinding(SecurityMode.TransportWithMessageCredential), new EndpointAddress(_stsAddress)); factory.TrustVersion = TrustVersion.WSTrust13; factory.Credentials.UserName.UserName = "middletier"; factory.Credentials.UserName.Password = "abc!123"; var rst = new RequestSecurityToken { AppliesTo = new EndpointAddress(_serviceAddress), RequestType = RequestTypes.Issue, KeyType = KeyTypes.Symmetric, ActAs = new SecurityTokenElement(bootstrapToken) }; var channel = factory.CreateChannel(); var delegationToken = channel.Issue(rst); return delegationToken; } HTH

Simple way of converting server side objects into client side using JSON serialization for asp.net websites

- by anil.kasalanati

Introduction:- With the growth of Web2.0 and the need for faster user experience the spotlight has shifted onto javascript based applications built using REST pattern or asp.net AJAX Pagerequest manager. And when we are working with javascript wouldn’t it be much better if we could create objects in an OOAD way and easily push it to the client side. Following are the reasons why you would push the server side objects onto client side - Easy availability of the complex object. - Use C# compiler and rick intellisense to create and maintain the objects but use them in the javascript. You could run code analysis etc. - Reduce the number of calls we make to the server side by loading data on the pageload. I would like to explain about the 3rd point because that proved to be highly beneficial to me when I was fixing the performance issues of a major website. There could be a scenario where in you be making multiple AJAX based webrequestmanager calls in order to get the same response in a single page. This happens in the case of widget based framework when all the widgets are independent but they need some common information available in the framework to load the data. So instead of making n multiple calls we could load the data needed during pageload. The above picture shows the scenario where in all the widgets need the common information and then call GetData webservice on the server side. Ofcourse the result can be cached on the client side but a better solution would be to avoid the call completely. In order to do that we need to JSONSerialize the content and send it in the DOM. Example:- I have developed a simple application to demonstrate the idea and I would explaining that in detail here. The class called SimpleClass would be sent as serialized JSON to the client side . And this inherits from the base class which has the implementation for the GetJSONString method. You can create a single base class and all the object which need to be pushed to the client side can inherit from that class. The important thing to note is that the class should be annotated with DataContract attribute and the methods should have the Data Member attribute. This is needed by the .Net DataContractSerializer and this follows the opt-in mode so if you want to send an attribute to the client side then you need to annotate the DataMember attribute. So if I didn’t want to send the Result I would simple remove the DataMember attribute. This is default WCF/.Net 3.5 stuff but it provides the flexibility of have a fullfledged object on the server side but sending a smaller object to the client side. Sometimes you may hide some values due to security constraints. And thing you will notice is that I have marked the class as Serializable so that it can be stored in the Session and used in webfarm deployment scenarios. Following is the implementation of the base class – This implements the default DataContractJsonSerializer and for more information or customization refer to following blogs – http://softcero.blogspot.com/2010/03/optimizing-net-json-serializing-and-ii.html http://weblogs.asp.net/gunnarpeipman/archive/2010/12/28/asp-net-serializing-and-deserializing-json-objects.aspx The next part is pretty simple, I just need to inject this object into the aspx page. And in the aspx markup I have the following line – <script type="text/javascript"> var data =(<%=SimpleClassJSON %>); alert(data.ResultText); </script> This will output the content as JSON into the variable data and this can be any element in the DOM. And you can verify the element by checking data in the Firebug console. Design Consideration – If you have a lot of javascripts then you need to think about using Script # and you can write javascript in C#. Refer to Nikhil’s blog – http://projects.nikhilk.net/ScriptSharp Ensure that you are taking security into consideration while exposing server side objects on to client side. I have seen application exposing passwords, secret key so it is not a good practice. The application can be tested using the following url – http://techconsulting.vpscustomer.com/Samples/JsonTest.aspx The source code is available at http://techconsulting.vpscustomer.com/Source/HistoryTest.zip

Using the StopWatch class to calculate the execution time of a block of code

- by vik20000in

Many of the times while doing the performance tuning of some, class, webpage, component, control etc. we first measure the current time taken in the execution of that code. This helps in understanding the location in code which is actually causing the performance issue and also help in measuring the amount of improvement by making the changes. This measurement is very important as it helps us understand the problem in code, Helps us to write better code next time (as we have already learnt what kind of improvement can be made with different code) . Normally developers create 2 objects of the DateTime class. The exact time is collected before and after the code where the performance needs to be measured. Next the difference between the two objects is used to know about the time spent in the code that is measured. Below is an example of the sample code. DateTime dt1, dt2; dt1 = DateTime.Now; for (int i = 0; i < 1000000; i++) { string str = "string"; } dt2 = DateTime.Now; TimeSpan ts = dt2.Subtract(dt1); Console.WriteLine("Time Spent : " + ts.TotalMilliseconds.ToString()); The above code works great. But the dot net framework also provides for another way to capture the time spent on the code without doing much effort (creating 2 datetime object, timespan object etc..). We can use the inbuilt StopWatch class to get the exact time spent. Below is an example of the same work with the help of the StopWatch class. Stopwatch sw = Stopwatch.StartNew(); for (int i = 0; i < 1000000; i++) { string str = "string"; } sw.Stop(); Console.WriteLine("Time Spent : " +sw.Elapsed.TotalMilliseconds.ToString()); [Note the StopWatch class resides in the System.Diagnostics namespace] If you use the StopWatch class the time taken for measuring the performance is much better, with very little effort.

Unobtrusive Client Side Validation with Dynamic Contents in ASP.NET MVC 3

- by imran_ku07

Introduction: A while ago, I blogged about how to perform client side validation for dynamic contents in ASP.NET MVC 2 at here. Using the approach given in that blog, you can easily validate your dynamic ajax contents at client side. ASP.NET MVC 3 also supports unobtrusive client side validation in addition to ASP.NET MVC 2 client side validation for backward compatibility. I feel it is worth to rewrite that blog post for ASP.NET MVC 3 unobtrusive client side validation. In this article I will show you how to do this. Description: I am going to use the same example presented at here. Create a new ASP.NET MVC 3 application. Then just open HomeController.cs and add the following code, public ActionResult CreateUser() { return View(); } [HttpPost] public ActionResult CreateUserPrevious(UserInformation u) { return View("CreateUserInformation", u); } [HttpPost] public ActionResult CreateUserInformation(UserInformation u) { if(ModelState.IsValid) return View("CreateUserCompanyInformation"); return View("CreateUserInformation"); } [HttpPost] public ActionResult CreateUserCompanyInformation(UserCompanyInformation uc, UserInformation ui) { if (ModelState.IsValid) return Content("Thank you for submitting your information"); return View("CreateUserCompanyInformation"); } Next create a CreateUser view and add the following lines, <%@ Page Title="" Language="C#" MasterPageFile="~/Views/Shared/Site.Master" Inherits="System.Web.Mvc.ViewPage<UnobtrusiveValidationWithDynamicContents.Models.UserInformation>" %> <asp:Content ID="Content1" ContentPlaceHolderID="TitleContent" runat="server"> CreateUser </asp:Content> <asp:Content ID="Content2" ContentPlaceHolderID="MainContent" runat="server"> <div id="dynamicData"> <%Html.RenderPartial("CreateUserInformation"); %> </div> </asp:Content> Next create a CreateUserInformation partial view and add the following lines, <%@ Control Language="C#" Inherits="System.Web.Mvc.ViewUserControl<UnobtrusiveValidationWithDynamicContents.Models.UserInformation>" %> <% Html.EnableClientValidation(); %> <%using (Html.BeginForm("CreateUserInformation", "Home")) { %> <table id="table1"> <tr style="background-color:#E8EEF4;font-weight:bold"> <td colspan="3" align="center"> User Information </td> </tr> <tr> <td> First Name </td> <td> <%=Html.TextBoxFor(a => a.FirstName)%> </td> <td> <%=Html.ValidationMessageFor(a => a.FirstName)%> </td> </tr> <tr> <td> Last Name </td> <td> <%=Html.TextBoxFor(a => a.LastName)%> </td> <td> <%=Html.ValidationMessageFor(a => a.LastName)%> </td> </tr> <tr> <td> Email </td> <td> <%=Html.TextBoxFor(a => a.Email)%> </td> <td> <%=Html.ValidationMessageFor(a => a.Email)%> </td> </tr> <tr> <td colspan="3" align="center"> <input type="submit" name="userInformation" value="Next"/> </td> </tr> </table> <%} %> <script type="text/javascript"> $("form").submit(function (e) { if ($(this).valid()) { $.post('<%= Url.Action("CreateUserInformation")%>', $(this).serialize(), function (data) { $("#dynamicData").html(data); $.validator.unobtrusive.parse($("#dynamicData")); }); } e.preventDefault(); }); </script> Next create a CreateUserCompanyInformation partial view and add the following lines, <%@ Control Language="C#" Inherits="System.Web.Mvc.ViewUserControl<UnobtrusiveValidationWithDynamicContents.Models.UserCompanyInformation>" %> <% Html.EnableClientValidation(); %> <%using (Html.BeginForm("CreateUserCompanyInformation", "Home")) { %> <table id="table1"> <tr style="background-color:#E8EEF4;font-weight:bold"> <td colspan="3" align="center"> User Company Information </td> </tr> <tr> <td> Company Name </td> <td> <%=Html.TextBoxFor(a => a.CompanyName)%> </td> <td> <%=Html.ValidationMessageFor(a => a.CompanyName)%> </td> </tr> <tr> <td> Company Address </td> <td> <%=Html.TextBoxFor(a => a.CompanyAddress)%> </td> <td> <%=Html.ValidationMessageFor(a => a.CompanyAddress)%> </td> </tr> <tr> <td> Designation </td> <td> <%=Html.TextBoxFor(a => a.Designation)%> </td> <td> <%=Html.ValidationMessageFor(a => a.Designation)%> </td> </tr> <tr> <td colspan="3" align="center"> <input type="button" id="prevButton" value="Previous"/> <input type="submit" name="userCompanyInformation" value="Next"/> <%=Html.Hidden("FirstName")%> <%=Html.Hidden("LastName")%> <%=Html.Hidden("Email")%> </td> </tr> </table> <%} %> <script type="text/javascript"> $("#prevButton").click(function () { $.post('<%= Url.Action("CreateUserPrevious")%>', $($("form")[0]).serialize(), function (data) { $("#dynamicData").html(data); $.validator.unobtrusive.parse($("#dynamicData")); }); }); $("form").submit(function (e) { if ($(this).valid()) { $.post('<%= Url.Action("CreateUserCompanyInformation")%>', $(this).serialize(), function (data) { $("#dynamicData").html(data); $.validator.unobtrusive.parse($("#dynamicData")); }); } e.preventDefault(); }); </script> Next create a new class file UserInformation.cs inside Model folder and add the following code, public class UserInformation { public int Id { get; set; } [Required(ErrorMessage = "First Name is required")] [StringLength(10, ErrorMessage = "First Name max length is 10")] public string FirstName { get; set; } [Required(ErrorMessage = "Last Name is required")] [StringLength(10, ErrorMessage = "Last Name max length is 10")] public string LastName { get; set; } [Required(ErrorMessage = "Email is required")] [RegularExpression(@"^\w+([-+.']\w+)*@\w+([-.]\w+)*\.\w+([-.]\w+)*$", ErrorMessage = "Email Format is wrong")] public string Email { get; set; } } Next create a new class file UserCompanyInformation.cs inside Model folder and add the following code, public class UserCompanyInformation { public int UserId { get; set; } [Required(ErrorMessage = "Company Name is required")] [StringLength(10, ErrorMessage = "Company Name max length is 10")] public string CompanyName { get; set; } [Required(ErrorMessage = "CompanyAddress is required")] [StringLength(50, ErrorMessage = "Company Address max length is 50")] public string CompanyAddress { get; set; } [Required(ErrorMessage = "Designation is required")] [StringLength(50, ErrorMessage = "Designation max length is 10")] public string Designation { get; set; } } Next add the necessary script files in Site.Master, <script src="<%= Url.Content("~/Scripts/jquery-1.4.4.min.js")%>" type="text/javascript"></script> <script src="<%= Url.Content("~/Scripts/jquery.validate.min.js")%>" type="text/javascript"></script> <script src="<%= Url.Content("~/Scripts/jquery.validate.unobtrusive.min.js")%>" type="text/javascript"></script> Now run this application. You will get the same behavior as described in this article. The key important feature to note here is the $.validator.unobtrusive.parse method, which is used by ASP.NET MVC 3 unobtrusive client side validation to initialize jQuery validation plug-in to start the client side validation process. Another important method to note here is the jQuery.valid method which return true if the form is valid and return false if the form is not valid . Summary: There may be several occasions when you need to load your HTML contents dynamically. These dynamic HTML contents may also include some input elements and you need to perform some client side validation for these input elements before posting thier values to server. In this article I shows you how you can enable client side validation for dynamic input elements in ASP.NET MVC 3. I am also attaching a sample application. Hopefully you will enjoy this article too.
